When installing HDDs and SSDs we start at the lowest numbered ports and go up. Why are your drives on Port 5 and 6? Could be trouble on some boards.
Also, when I start a new build the BIOS is always made current because issues like HDD compatibility and more are often fixed over time.
Hi. I've just built myself a new system using an Asus Prime 7270-A motherboard. I have successfully installed an SSD drive and have successfully installed Windows 10 (64 bit) on this. I am now trying to install additional HDDs. I have wired in a brand new (non-formatted) 1TB WD Blue drive. The connections appear to be fine and the drive is recognized by the BIOS. It is not recognized by Windows. Not only does in not show up under "my computer", it does not show up under disk management or any of the system administrative tools. I've tried every trick I can find on the internet and nothing seems to work. What am I missing? ANY thoughts would be greatly appreciated. Cheers.
